Summary
| DescriptionHelmholtz-Kohlrausch effect visualized improved.png |
English: Each color on top has the——same luminance level. And yet they do not look the "same." When the top image is converted——to grayscale using luminance (sRGB linearized (0.22 × R) + (0.72 × G) + (0.06 × B)), we have the image on the bottom.
The colors are #f80000, #768300, #008e5c, #0082c5, #d400ea. |
